The different elements are:
3-point Round Robins:
Groups of 4, 5 or 6 players playing each other in matches to 3 points;
Tric Trac Tournos (modified):
Groups of up to 10 players playing each other in single game matches, with a points system which rewards gammons and backgammons a little more than usual;
DMP Tournos:
Groups of up to 10 players playing each other in single game matches (i.e. double match point).
Nackgammon Tournos:
Groups of 4, 5 or 6 players playing each other in single game matches where the starting positions of the checkers are varied from the norm to give a game with greater contact; gammons and backgammons count in this format.
SuperNackgammon Tournos:
Groups of 4, 5 or 6 players playing each other in single game matches where the starting positions of the checkers are varied from the norm to give a game with greater contact (with contact more exaggerated than in Nackgammon Tournos); gammons and backgammons count in this format.
In 3-point Round Robins, Nackgammon Tournos and SuperNackgammon Tournos players will form a single group, or be split into multiple groups, depending on the total number of entries as follows:
4, 5, 6 or 7 players form a single group;
8, 9, 10, 11 or 12 players form two equal, or nearly equal, groups;
13, 14, 15, 16, 17 or 18 players form three equal, or nearly equal groups;
and so on;
non-paying players will be spread evenly between the groups.
In Tric Trac Tournos (modified) and DMP Tournos players will form a single group, or be split into multiple groups, depending on the total number of entries as follows:
6, 7, 8, 9, 10 or 11 players form a single group;
12, 13, 14, 15, 16, 17, 18, 19 or 20 players form two equal, or nearly equal, groups;
and so on;
non-paying players will be spread evenly between the groups.
But where there are only 4 or 5 players present, the Tric Trac Tournos (modified) or DMP Tournos will be abandoned and a single 3-point round robin substituted.
